It is also an object of the present invention to provide a grating equipped with an opening and closing means that the opening and closing means are flipped and the grating is automatically opened to drain the water when the rain water is collected in the grating in the state that the opening and closing means is blocking the grating.

The present invention proposed to address the above object,

It includes an outer frame portion of the rectangular frame shape formed with an upper and lower opening portion, and a support frame for connecting the inner side facing each other of the outer frame,

It is installed on the lower open portion of the outer frame portion is characterized in that it further comprises an opening and closing means for opening and closing the lower open portion through self-rotation.

And the opening and closing plate is made up of the first and the second opening and closing plate is located so that the intermediate point is facing each other, the folding portion is connected between the opening and closing plate in the state located between the first and second opening and closing plate It is made in the form of a rotating shaft, each opening and closing plate is characterized in that rotated around the rotating shaft, respectively.

In addition, the opening and closing plate is made of a waterproof material, the upper surface of the opening and closing plate is characterized in that the absorbent material is provided.

The present invention having the above characteristics,

According to the drainage, the opening and closing means to selectively open and close the lower opening of the grating when the drainage is not made always has the advantage of preventing the input of the waste and the backflow of the odor in the sewer.

In addition, when the rainwater is collected in a certain amount in the grating, the opening and closing means are automatically flipped to open the grating has the advantage that the drainage can be made automatically smoothly.

Hereinafter, with reference to the configuration illustrated in the drawings will be described an embodiment of the overall configuration and its operation of the present invention.

The present invention is largely configured to include the outer frame portion 10, the support frame 20, opening and closing means 2000, as shown in [2] and [3].

First of all, the outer frame part 10 serves as the entire bone band of the grating 100 and has a rectangular ring shape in which the upper and lower sides of the outer frame part are opened.

At this time, the through-hole 12 for the installation of the opening and closing plate to be described later is formed in the lower front and rear of the outer frame portion 10. As will be described later, when the folding unit 2200 is welded to the outer frame unit 10, the through hole 12 may not be formed.

The support frame 20 is installed inside the outer frame part 10, and the support frame 20 serves to divide a partition between the outside and the drain hole 1000, and has a simple rectangular bar shape and both ends of the outer frame. It is fixed to both inner side surfaces of the part 10.

Each of the support frames 20 are spaced apart from each other and drained through the gaps between the support frames 20.

The structure described above is the same structure as the general grating, in the present invention, a separate opening and closing means 2000 is further provided in the grating 100.

The opening and closing means 2000 is for opening and closing the lower open portion of the grating 100, and is composed of the opening and closing plate 2100, the folding portion 2200, and the elastic means 2300.

First, the opening and closing plate 2100 is a part having an opening and closing function of the grating 100 substantially, and is manufactured to have an area substantially the same as that of the lower open part of the grating 100, and the material is non-permeable such as metal or plastic. It is made of a material with properties.

The opening and closing plate 2100 is divided into left and right on the basis of the intermediate point is divided into a first opening and closing plate 2110 and a second opening and closing plate 2120 which are later rotated separately from each other.

At this time, the shaft hole 2112 is formed through the front and rear surfaces of the second opening and closing plate 2120 side of the first opening and closing plate 2110, and the coupling groove 2114 for joining the second opening and closing plate 2120 is formed at the intermediate point. It is formed and the installation groove 2116 for the installation of the elastic means 2300 to be described later is formed in front and rear of the coupling groove (2114).

In addition, at the end portion of the second opening and closing plate 2120 facing the first opening and closing plate 2110, a coupling piece 2122 inserted into the coupling groove 2112 of the first opening and closing plate 2110 is formed to protrude and the coupling piece ( 2122, the shaft hole 2124 is also formed through.

Thus, the first and second opening and closing plate (2110, 2120), as shown in the [Fig. 3] and [Fig. 5], the coupling piece 2122 is inserted into the coupling groove 2112, one end is joined to each other and each opening and closing plate ( The shaft holes 2116 and 2124 of 2110 and 2120 are in communication with each other.

The first and second opening and closing plates 2100 and 2200 are finally connected to each other through a separate folding part 2200, and the folding parts 2200 are formed in a simple shaft shape and communicate with each shaft hole 2116 and 2124. As the penetrating through (2) at the same time, the first and second opening and closing plate (2110, 2120) is connected to each other to enable a separate rotation around the folding portion (2200).

In this state, each opening and closing plate 2110 and 2120 is further provided with an elastic means 2300 for imparting a restoring force to the original position after the rotation, the elastic means 2300 is a general torsion spring (torsion spring) form, that is, A torsion bar 2310 is drawn out to the left and right at both upper and lower ends of the middle coil part.

The elastic means 2300 is located in each of the front and rear installation grooves 2116 of the first opening and closing plate 2110, in detail, each of the elastic means (2300) prior to penetrating the folding portion 2200, the corresponding installation groove After each location 2116, the folding unit 2200 is installed to penetrate each of the opening and closing plates 2110 and 2120 and the elastic means 2300.

The upper and lower torsion bars 2310 of the elastic means 2300 installed in this way are in close contact with each other on the first opening and closing plate 2110 and the second opening and closing plate 2120.

For reference, when the elastic means 2300 is implemented in the form of a torsion spring, the installation structure is not necessarily limited thereto, and as shown in FIG. 4, the installation groove 2116 is disposed on the coupling piece 2122 of the second opening and closing plate 2120. It may be formed so that the elastic means is positioned in the center.

The opening and closing means 2000 of the present invention implemented as described above is connected to each other without being inserted into the front and rear through holes 12 formed in the outer frame portion 10 or forming the through holes.

Therefore, as shown in FIGS. 3 and 5, the first and second opening and closing plates 2110 and 2120 completely block the lower open part of the outer frame part 10.

Hereinafter will be described the operation of the present invention.

As the lower end of the grating 100 is blocked by each opening and closing plate 2110 and 2120 as shown in FIG. 5, rainwater does not immediately enter a drain hole but is collected inside the grating when raining.

As the amount of water collected increases, each opening and closing plate 2110 and 2120 rotates around the folding portion 2200 by the load of the collected rainwater, so that the lower side of the grating is opened and the rainwater is drained to the drain. do.

When the opening and closing plates 2110 and 2120 are rotated in this way, the torsion bars 2310 of the elastic means 2300 are also flipped together, and when the drainage is completed, the load applied to each of the opening and closing plates 2110 and 2120 disappears. As the elastic force of the elastic means 2300 is transmitted to each opening and closing plate 2110 and 2120 through each torsion bar 2310, each opening and closing plate 2110 and 2120 are rotated to their original positions, as shown in FIG. Again, the bottom of the grating 100 is blocked.

After that, when the rainwater is collected again, a certain amount of water is drained automatically by repeating the above process.

When the rain does not fall and no drainage is required, the grating 100 is always blocked as shown in the drawing. Thus, the thrown garbage is not placed in the drainage path and is positioned on the opening and closing plate 2100. Therefore, when cleaning the surroundings, it is necessary to pick up and process the garbage in the grating 100, thereby preventing the phenomenon of garbage accumulating in the drain.

In addition, as the opening and closing plate 2100 blocks the grating 100, odors in the drain pipe may be prevented from rising to the outside through the grating.

As described above, in the present invention, when drainage is required in rainy days, drainage is automatically performed, but when drainage is not necessary, the grating is always blocked to block waste inflow into the drainage path, and at the same time, odors in the drainage pipe flow back to the outside. The key is to make it possible.

Among the opening and closing means 2000 of the present invention, in particular, the structure of the elastic means 2300 may be implemented in various forms. [7] and [FIG. 8] show a second embodiment of the modified structure. As can be seen in the drawings, the basic configuration of the opening and closing means is the same, it is characterized in that the elastic means is implemented in the form of a band spring (band spring) rather than a torsion spring.

In this case, both ends of each of the semi-circular band springs 2300a are fixed to the folding part 2200 exposed on the installation groove 2116 by welding or the like.

Therefore, as shown in FIG. 8, when the opening and closing plates 2110 and 2120 are rotated, the respective band springs 2300a are also flipped around the fixed portion with the folding portion 2200, and then each opening and closing plate 2110 and 2120 is later opened. It is possible to impart an elastic force.

Of course, instead of implementing the band spring in a separate semicircle form, it can be implemented in the form of fixing the intermediate point on the foldable part 2200 by producing a single circle.

Since the band spring has a lower resistance than the torsion spring, even if the amount of rainwater collected in the grating is small, the opening and closing plates 2110 and 2120 can be easily rotated and opened, thereby reducing the drainage interval.

9 and 10 illustrate a third modified example of the present invention, in which the elastic means is implemented in the form of a general tension spring 2300b.

Referring to the installation structure as shown in [Fig. 9] the upper end of each tension spring (2300b) is connected to the inner side of the outer frame portion 10, the lower end is connected to one side upper surface of each opening and closing plate (2110, 2120). .

Therefore, as shown in FIG. 10, when the opening and closing plates 2110 and 2120 are rotated downward, the respective tension springs 2300b are also tensioned, and when the draining is completed, the opening and closing plates are returned to their original positions by the contracting force of each of the tension springs 2300b. Return to.

11 is a view showing an embodiment in which a separate absorbent member 3000 is attached on the opening and closing plates 2110 and 2120. In the above-described embodiments, the opening and closing is opened by a self stress of the elastic means 2300. Since the plate 2100 is in a supported state, the rainwater must be collected in the grating 100 by a predetermined amount or more, but the opening and closing plate 2100 is rotated.

However, as the absorbent member 3000 is provided on the opening and closing plate 2100 as described above, since the load applied to the opening and closing plate 2100 is quickly increased by absorbing the rainwater falling by the absorbent member 3000 as it is, the rainwater is grating ( Before the water is collected in 100, the opening and closing plate 2100 is rotated to have an advantage that the drainage can be made quickly.

In addition to the above embodiments, the type and installation structure of the elastic means of the present invention may be applied any number of modifications as long as the structure can transmit the restoring force to each of the pivoting opening and closing plates.

In addition, the overall features of the present invention can also be implemented by various modifications and combinations by those skilled in the art, but such modifications and combinations are provided with a separate opening and closing means in general grating to automatically open when drainage is required, and usually shut off by inflow of waste or If it is related to the configuration and purpose to block the backflow of the drain odor should be considered to fall within the protection scope of the present invention.
